ABSTRACT:
The detection of "significant bacteriuria" in a urine sample is accomplished by measuring the head space gas oxygen consumption in a closed vial system. A sample to be tested is introduced into a sealed vial containing a growth medium and the head space gas oxygen concentration initially measured. After a suitable incubation period, the oxygen concentration above the sample is again measured using a closed sample loop. A decrease in the head space oxygen concentration below a predetermined level indicates the presence of a significant quantity of oxygen consuming microorganisms in the sample.
